Unifi AC: remove bs-partition ro-flag 

This patch allows to modify the bs-partition on the AC Mesh.

Without the patch, the bs partition on the AC Mesh is locked
forever. This can be a problem if
a) the bs partition has not been updated correctly during initial flash
b) the sysupgrade mechanism is altered by OpenWRT in order to account for
the flip flop layout

Subject: [PATCH] ar71xx: remove bs-partition ro-flag for UniFi AC
This removes the read-only flag from the bs (bootselect) partition
on UniFi AC devices. This allows to correct the indicator from which
partition the device is booting its kernel from.
